연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An air admittance vent diaphragm assembly is disclosed. The assembly comprises a base, an annular retainer ring, and an annular malleable washer. The base has an annular portion and a stem extending orthogonally from the center of the annular portion. The annular retainer ring includes a circumferential skirt engaged with an outer perimeter of the annular portion of the base, with the stem extending beyond the annular retainer ring. The annular malleable washer is disposed between the annular retainer ring and the annular portion of the base.

What is claimed is: 1. An air admittance vent diaphragm assembly comprising: a base having an annular portion and a stem extending orthogonally from a center of the annular portion; an annular retainer ring having a circumferential skirt, wherein the circumferential skirt engages the base about an outer perimeter of the annular portion and the stem extends beyond the annular retainer ring; and an annular malleable washer disposed between the annular retainer ring and the annular portion; wherein the annular portion includes a stepped surface; and wherein the stepped surface includes an outer step and an inner step, the outer step being disposed nearer to the annular retainer ring than the inner step. 2. The diaphragm assembly of claim 1, wherein the stem has a substantially X-shaped cross section. 3. The diaphragm assembly of claim 1, wherein the outer perimeter includes a beveled edge. 4. The diaphragm assembly of claim 3, wherein the circumferential skirt includes a lip and the lip engages the beveled edge. 5. The diaphragm assembly of claim 1, wherein the annular portion includes a first circumferential ridge and a side of the annular retainer ring facing the annular portion includes a second circumferential ridge. 6. The diaphragm assembly of claim 5, wherein the first and second circumferential ridges have different radii. 7. The diaphragm assembly of claim 1, wherein the base and the annular retainer ring, in combination, include means for the outer perimeter of the annular portion and the circumferential skirt of the annular retainer ring to mutually engage. 8. The diaphragm assembly of claim 1, wherein the base includes means for providing the washer with space for limited bi-directional longitudinal movement. 9. The diaphragm assembly of claim 1, wherein the base and the annular retainer ring, in combination, include means for providing an airtight seal between the base, the annular retainer ring, and the annular malleable washer. 10. The diaphragm assembly of claim 1, wherein the stem has a lateral cross sectional shape adapted to increase airflow through an air admittance vent opening while maximizing an effective circumference of the stem within the air admittance vent opening. 11. The diaphragm assembly of claim 1, wherein the base includes means for providing the washer with space for limited bi-directional longitudinal movement. 12. The diaphragm assembly of claim 1, wherein the stem has a lateral cross sectional shape adapted to increase airflow through an air admittance vent opening while maximizing an effective circumference of the stem within the air admittance vent opening. 13. An air admittance vent diaphragm assembly comprising: a base having an annular portion and a stem extending orthogonally from a center of the annular portion, the stem having a substantially X-shaped cross section, wherein an outer perimeter of the annular portion includes a beveled edge; an annular retainer ring having a circumferential skirt, wherein the circumferential skirt engages the base about an outer perimeter of the annular portion and the stem extends beyond the annular retainer ring; and an annular malleable washer disposed between the annular retainer ring and the annular portion. 14. An air admittance vent diaphragm assembly comprising: a base having an annular portion and a stem extending orthogonally from a center of the annular portion, the annular portion including a first circumferential ridge and having a stepped surface; an annular retainer ring having a circumferential skirt, wherein the circumferential skirt engages the base about an outer perimeter of the annular portion and the stem extends beyond the annular retainer ring, and wherein a side of the annular retainer ring facing the annular portion includes a second circumferential ridge; and an annular malleable washer disposed between the annular retainer ring and the annular portion. 15. The diaphragm assembly of claim 14, wherein the first and second circumferential ridges have different radii. 16. The diaphragm assembly of claim 14, wherein the stepped surface includes an outer step and an inner step, the outer step being disposed nearer to the annular retainer ring than the inner step. 17. An air admittance vent diaphragm assembly comprising: a base having an annular portion and a stem extending orthogonally from a center of the annular portion, the stem having a substantially X-shaped cross section, and the annular portion includes a first circumferential ridge and has a stepped surface; an annular retainer ring having a circumferential skirt, the stem extending beyond the annular retainer ring, wherein a side of the annular retainer ring facing the annular portion includes a second circumferential ridge, the first and second circumferential ridges having different radii, and wherein the stepped surface includes an outer step and an inner step, the outer step being disposed nearer to the annular retainer ring than the inner step; and an annular malleable washer disposed between the annular retainer ring and the annular portion. 18. The diaphragm assembly of claim 17, wherein an outer perimeter of the annular portion includes a beveled edge; and wherein the circumferential skirt comprises a lip, the lip engaging the beveled edge. 19. An air admittance vent diaphragm assembly comprising: a base having an annular portion and a stem extending orthogonally from a center of the annular portion; an annular retainer ring having a circumferential skirt engaged with an outer perimeter of the annular portion, the stem extending beyond the annular retainer ring, wherein the base and the annular retainer ring, in combination, include means for the outer perimeter of the annular portion and the circumferential skirt of the annular retainer ring to mutually engage; and an annular malleable washer disposed between the annular retainer ring and the annular portion; wherein the base and the annular retainer ring, in combination, include means for providing an airtight seal between the base, the annular retainer ring, and the annular malleable washer; wherein the annular portion includes a stepped surface; and wherein the stepped surface includes an outer step and an inner step, the outer step being disposed nearer to the annular retainer ring than the inner step. 20. An air admittance vent diaphragm assembly comprising: a base having an annular portion and a stem extending orthogonally from a center of the annular portion, the stem having a lateral cross-sectional shape adapted to increase airflow through an air admittance vent opening while maximizing an effective circumference of the stem within the air admittance vent opening; an annular retainer ring having a circumferential skirt engaged with an outer perimeter of the annular portion, the stem extending beyond the annular retainer ring; and an annular malleable washer disposed between the annular retainer ring and the annular portion; wherein the base includes means for providing the washer with space for limited bi-directional longitudinal movement; wherein the annular portion includes a stepped surface; and wherein the stepped surface includes an outer step and an inner step, the outer step being disposed nearer to the annular retainer ring than the inner step.
